A Complete Guide To Window Replacement

A Complete Guide To Window Replacement

Windows are often looked over, so many homeowners don't even realize that they are in dire need of window replacement. Consequently, many people don't even know what to expect from the whole process. Window replacement projects are time-consuming and expensive, so you need to do your research beforehand.

Hence, we have prepared a complete window replacement guide to help you through the process.

Signs You Need Window Replacement:

First, you need to evaluate your home for any such signs. There are many signs which indicate that it is time for window replacement. Most of these signs can be spotted easily.

Broken Window Frame:

If the window glass is broken, that can be easily replaced. The same cannot be expected from the window frame. If the frame is either broken or pulling away from the wall, that is a definite indication for replacement.

Drafty Windows And Poor Energy Efficiency:

Have you noticed air coming into your room, even when all the doors and windows are closed? Upon further investigation, it will become clear that the air is coming from the windows. This is a concerning matter because it can also drastically increase your energy bills. As the treated air is escaping outside, your HVAC system would need to work overtime to compensate for that.


The formation of condensation and snow on either side of the window is a direct sign of poorly insulated windows. 

Cold To Touch:

Single paned windows will always feel cold. But if double paned windows are cold, something is wrong. Usually, they should be mildly cold, even in freezing temperatures.

Unable To Repair:

Windows can be repaired and painted with ease. But when you realize that repair is not enough, that is a telling sign. If repair costs you more than 30% of its original price, invest in replacement windows.

Reasons For Window Replacement:

In addition to above mentioned points, here are some other reasons for investing in window replacement.

High Energy Bills:

If your windows are not sealed in the correct manner, they can become drafty. In that instance, they would allow the cool air to escape outside in the summers. In winters, the thermal efficiency of your home will decrease due to cold air coming in. In both cases, the heating and cooling systems will need to work overtime to maintain the optimal temperature of your home. Consequently, this will increase energy consumption, which will lead to high electricity and gas bills.

Old Age:

Everything has its own life, and window materials are similar in this regard. With the passage of time, wear and tear are apparent on the window, indicating that it is a time of change.

Increasing Resale Value:

Who will buy a home with broken, drafty windows? That's right, no one unless they are planning on the renovation on their own. You won't get a reasonable price for your property in both cases because it has a visible shabby structure.


Reinforced windows will provide more protection.

Adds Aesthetic Value:

Newly replaced windows look beautiful.

Improving Natural And Ventilation:

With the help of replaced windows, you can considerably improve the ventilation and lighting of your home. 

Selecting Materials For Replacement Window:

When looking for a window replacement, you need to choose the right type of material for your home.


Aluminum windows are known for their strength and durability. Windows made of this material have many advantages, like resistance to insects, no rotting, economical, lightweight, and less need for repainting and maintenance. But it has some glaring disadvantages, like being a poor material for energy efficiency susceptible to corrosion when exposed to salty air.


Vinyl windows are the most famous option, and there is a good reason for that. The material is durable, low maintenance, easy to clean, lightweight, and easy to install. Additionally, it won’t corrode, which gives it its characteristic long lifespan. However, its energy efficiency properties earned it its well-deserved fame.


Wooden windows are used for classic or traditional architecture. With their naturally warm hues, they give a home, natural vibe. But you don't have to stick with the brown color; you can have it painted to match your décor. Its advantages include insulation, condensation prevention, and ease of customization. On the contrary, the list of disadvantages is long; susceptible to rotting, termites, warping, and high maintenance. But even with all of that, it is still one of the most commonly used materials.


Fiberglass is another popular window material, and for a good reason. It won’t peel, fade, flake, expand or contract in high temperature, durable, rigid, and absorb liquid. But it is expensive, and if constructed wrong, drafts can form in the frame surroundings.


The last option is using composite materials made of vinyl and reclaimed wood blend. The material is specially treated to resist warping, rotting, moisture damage, and warping. They are also great options for thermal and energy efficiency and are highly durable. However, it is the most expensive material out of all others.

Selecting Right Window Style:
